We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).

An anonymous reader writes "Mitsubishi was the last hold-out in the big-screen rear-projection display business after Samsung left the category in 2009. Now Mitsubishi has dropped the dinosaur. Every big-brand CE manufacturer got their start in the big-TV business via rear projection sets from CRT to DLP to LCoS, eventually replacing them with modern-day flat screens. Mitsubishi did develop LCD flat-screens for a time, but dropped out of that market to focus on rear DLPs after Samsung gave it a monopoly. The author, a CE editor, takes a nostalgic and amusing look at her 15 years with three Mitsu rear pros, the only big-screen TV she's known."

An anonymous reader writes "When I was younger, engineering and science offices didn't have computers yet. It was the tradition: Piled Higher and Deeper desks, and overloaded bookcases. I ended up doing other things, and haven't been in a regular office for a couple of decades. Now I'm older, spending a lot more time with the screen, and finding my aging butt and back aren't as pliable for the long hours of reading papers. And while looking at rather expensive chairs, etc for a solution, what I'm remembering is we used to be able to lean back, feet up, while reading the stapled print-outs — makes a change from hunched-over writing and typing. So I'm what wondering is this: Are We There Yet with tablets? You guys would know — What makes a good tablet for reading, sorting, annotating, and searching PDFs, etc? Hardware and software — what tablets have gotten this really right?"

McGruber writes "The Wall Street Journal has an article about Theresa Christy, a mathematician who develops algorithms for Otis Elevator Company, the world's largest manufacturer and maintainer of people-moving products including elevators, escalators and moving walkways. As an Otis research fellow, Ms. Christy writes strings of code that allow elevators to do essentially the greatest good for the most people — including the building's owner, who has to allocate considerable space for the concrete shafts that house the cars. Her work often involves watching computer simulation programs that replay elevator decision-making. 'I feel like I get paid to play videogames. I watch the simulation, and I see what happens, and I try to improve the score I am getting,' she says."

hypnosec writes "The Raspberry Pi Foundation has announced that the cheaper variant of the Raspberry Pi — the Model A — has entered production phase. Model A of the credit-card sized computer has been stripped of its Ethernet port and a USB port, leaving just one USB port. This model comes with 256MB RAM, but as it is less complex compared to its predecessor it will consume less power, thus opening up quite a few new usage scenarios. The Foundation has posted the first image of the $25 Model A on its site and noted 'We're anticipating that those of you who buy the Model A will be using it for different applications from Model B owners.'"

dcblogs writes "The U.S. Dept. of Energy has set a goal to develop battery and energy storage technologies that are five times more powerful and five times cheaper within five years. DOE is creating a new center at Argonne National Laboratory, at a cost of $120 million over five years, that's intended to reproduce development environments that were successfully used by Bell Laboratories and World War II's Manhattan Project. 'When you had to deliver the goods very, very quickly, you needed to put the best scientists next to the best engineers across disciplines to get very focused,' said U.S. Energy Secretary Stephen Chu, on Friday. The Joint Center for Energy Storage Research isn't designed to seek incremental improvements in existing technologies. This technology hub, according to DOE's solicitation (PDF), 'should foster new energy storage designs that begin with a "clean sheet of paper" — overcoming current manufacturing limitations through innovation to reduce complexity and cost.' Other research labs, universities and private companies are participating in the effort."

Volanin writes "I have been using Linux for the last 15 years both at home and at work (mostly GNOME and now Unity). Recently, I gave in to temptation and bought myself a Macbook retina 15". As you can read around, Linux still has no good support for this hardware, so I am running it inside a virtual machine. Running in scaled 1440x900 makes the Linux fonts look absolutely terrible, and running in true 2880x1800 makes them beautiful, but every UI element becomes so tiny, it's unworkable. Is there a desktop environment that handles resolution independence better? Linux has had support for SVG for a long time, but GNOME/Unity seems adamant in defining small icon sizes and UI elements without the possibility to resize them."

dryriver sends this quote from a BBC report:
"Imagine treating your phone like a piece of paper. Roll it up. Drop it. Squish it in your backpack. Step on it — without any damage. Researchers are working on just such handsets — razor-thin, paper-like and bendable. There have already been prototypes, attracting crowds at gadget shows. But rumors abound that next year will see the launch of the first bendy phone. Numerous companies are working on the technology — LG, Philips, Sharp, Sony and Nokia among them — although reports suggest that South Korean phone manufacturer Samsung will be the first to deliver. Samsung favors smartphones with so-called flexible OLED (Organic Light Emitting Diode) technology, and is confident that they will be 'very popular among consumers worldwide.' Their screens will be 'foldable, rollable, wearable and more, [and] will allow for a high degree of durability through their use of a plastic substrate that is thinner, lighter and more flexible than conventional LCD technology,' says a Samsung spokesperson.'"

eldavojohn writes "This holiday season I will return to the land of my childhood. It is flat and desolate with the nearest major city being a three hour car drive away. Although being able to hear the blood pulse through your ears and enjoying the full milky way is nice, I have finally convinced my parents to get "the internet." It's basically a Verizon Jetpack that receives 4G connected to a router. My mom says it works great but she has complained of it cutting in and out. I know where the tower is, this land is so flat and so devoid of light pollution that the tower and all windmills are supernovas on the horizon at night. Usually I use my rooted Galaxy Nexus to read Slashdot, reply to work e-mails, etc. I would like to build an antenna for her 4G device so they can finally enjoy information the way I have. I have access to tons of scrap copper, wood, steel, etc and could probably hit a scrap yard if something else were needed. As a kid, I would build various quad antennas in an attempt to get better radio and TV reception (is the new digital television antenna design any different?) but I have no experience with building 4G antennas. I assume the sizes and lengths would be much different? After shopping around any 4G antenna costs way too much money. So, Slashdot, do you have any resources, suggestions, books, ideas or otherwise about building something to connect to a Jetpack antenna port? I've got a Masters of Science but it's in Computer Science so if you do explain complicated circuits it helps to explain it like I'm five. I've used baluns before in antenna design but after pulling up unidirectional and reflector antenna designs, I realize I might be in a little over my head. Is there an industry standard book on building antennas for any spectrum?"

cylonlover writes "Exploring the regions of deep space beyond Mars means sending probes where solar power isn't practical. Since the 1960s, NASA has equipped its Apollo missions and unmanned explorers with Radioisotope Thermal Generators (RTGs). These have worked very well, but they run on plutonium 238, which is currently in short supply. Therefore, the Los Alamos National Laboratory is developing a new small nuclear reactor for spacecraft that uses uranium instead of plutonium to power Stirling engines and generate electricity. At the Nevada National Security Site's Device Assembly Facility near Las Vegas, engineers from Los Alamos, the NASA Glenn Research Center and National Security Technologies LLC conducted a Demonstration Using Flattop Fissions (DUFF) experiment that produced 24 watts of electricity using a pair of free-piston Stirling engines."

eldavojohn writes "Mojang's Marcus Persson (better known as 'Notch') has answered quite a few questions in an interview with PC Gamer about his new game 0x10c. Since its announcement, there's been very few details about game play aside from the DCPU-16 and art tests. But in this interview, Notch has revealed quite a bit about how the game will function and non-final ideas he has for either a monthly fee to play in a 'multiverse' or micropayments. He talks about a custom OS people are working on to load into the game's CPU as well as a an in-game 3D printer that will allow you to make virtual objects. When asked about Kickstarter and his Oculus dev kit, Notch said 'Definitely going to make it work in 0x10c no matter what' and his account of using the Oculus Rift sounds more than promising for the VR Device. When asked about Linux he said, '[Linux] is wonderful. I think we need to have it, and it's a shame that more people, including myself, don't use it. It's gotten easier and friendlier.' When asked about Microsoft he said, 'I use their OS – Windows 7 is an amazing operating system in my opinion and of course there's the Xbox, which I love. I'm sure Bing is going to take off and save them. [Editor's note: Notch is smiling mischievously as he says this.]'"

jfruh writes "Automakers are striving mightily to bring their in-dash systems into the modern age, providing integration with smartphones and other advanced features. The problem: while smartphones go in and out of vogue every few years, modern cars have lifespans of a decade or more. Add in the fact that many (though not all) manufacturers have no plans to allow software upgrades to their systems, and you might end up driving a car with a fancy in-dash computer system that's completely useless for much of the time you own it."

Probably -- if the device I want supports itProbably -- if it works as promisedProbably -- credit cards will be like checks in another decadeNot sure -- no strong opinions either wayDoubtful -- not a useful technology to meDoubtful -- it will be too fragmentedDoubtful -- privacy/security concernsDoes throwing my spare change at the cashier count as mobile?
